A curved ergonomic pen which facilitates writing on vertical surfaces comprises a housing having a barrel portion and a web portion. The barrel has curved inner and outer edges and substantially flat sides. The web is substantially flat and extends along the curved inner edge of the barrel. A curved channel is formed in the barrel in communication with openings in opposite ends of the barrel. A pair of ink cartridges each comprising an ink tube and a tip secured to one end thereof are retractably secured within the channel such that the respective tips generally extend toward opposite ends of the barrel. The pen tips are selectively extendable and retractable through the associated openings in the opposite ends of the barrel. In one embodiment, a note pocket for receiving relatively small sheets of paper is removably securable within a slot extending into an outer edge of the web. A cover is provided which is removably securable to the housing to cover both ends of the housing and any tips extending therefrom.
